They can press in a direction that tries to see how far their feral nature can go before they forsake writing a worthwhile song, which " Sudor Frio" flirts with. At 41 seconds they do not give themselves time to develop "Mal De Ojo: into anything of note. Not that they need much more time as they prove with "Arson Repent" which is only 20 longer, and more of a fully realized song. The more thrash influenced riffs could be seen as hard core who is not aware of how those genres intermingled in the 80s. "Ciego 'feels more like death metal to me. The same could be said of the song that follows though it is a one-dimensional exercise in hyper aggression. How much can you do to make a song that is is under a minute. It is like talking in incomplete sentences. A "Refugio" that follows sounds like it should be a part of this song. The two minute "Deny Disgrace" seems like it is the perfect length for what they are doing and is one of the album's songs. The 39 second "song" after it is like a cool thought that never became a song.
When they give into their thrashing impulses for "Rabia" it is a winning formula though the brutality overtakes it thanks to the machine gun drumming that is to blame. The last two songs find them getting caught up in the rapid-fire assault rather than their catchier thrash side that has hooky riffs. I will round this down to an 8 as I feel they could have done better and have the potential to do better in terms of songwriting as they strike the mark here enough to let me know.
